You can change your locale settings by editing the config.json file or using the pimatic build-in editor.
To set the locale and language of your pimatic installation, you need to add the locale option directly into the settings area:
settings": {
"locale": "de",
"httpServer": {
"enabled": true,
"port": 80
},
...
possible locales are: "en", "de", "es", "nl".
